I found an online community for wine enthusiasts that I really like which lets you create a virtual cellar of the wine you own for free. Snooth, it's fantastic! If you choose to, you can search for the wines you own and see the associated tasting notes, recommended "drink by" dates, price, and the opinions of others who have experienced the wine.
You can follow your favorite wineries announcements and of course, sign up for a plethora of email subscriptions according to your interests. Another thing I like about the site is that recommendations of wines to try will be suggested based upon the wines you rate.
Snooth.com has a welcoming interface, it's friendly and approachable. I will look forward to using it as the source I go to for cataloging my favorites.
